In 1959, Scott published his book “Cryogenic Engineering” (Scott, 1959), as a record of the research findings and
thinking that he and his colleagues had achieved in cryogenics, in the first five years of unclassified operation at the
NBS. In his chapter on ‘Storing and Transporting Liquefied Gases’, he considered the concept of the vapour-cooled
vent tube. He observed that the cold available in a cryogenic vapour for absorbing heat inflows can be many times

larger than the latent heat of evaporation of the cryogenic liquid. He further stated that “in those cases in which heat
conduction through the supports or vent tubes is a substantial part of the total, it may be worthwhile to use the
escaping vapour to intercept part of the heat”. He was indeed sowing the seeds for developing CryoFD as a major
support for cryogenic technology
